We will never end in the star trek branch until energy and resources in general are abundantly cheap and uncontested. Even in Star Trek, the canon is still that next to whole modern part of society, even on earth, there still exists classes. It’s just that the TV series depict the upper class: everyone working for the federation and star fleet.

I’m pretty sure they are using Star Trek as “generic human spacefaring utopian future”. As i said above, you could insert “luxury gay space communism” in there and still have the same meaning.
